Angel Raich is a 41 year-old mother of two who suffers from scoliosis, a brain tumour, chronic nausea and other ailments. Her doctor recommended eating or smoking marijuana every couple of hours to ease her pain and boost her appetite as she had no relief from conventional drugs.

Although she’s using marijuana for all the right medical reasons, being the only drug that keeps her alive, she is still not immune to the federal prosecution on drug charges.

The US supreme court ruled against Ms Raich two years ago noting that medical marijuana users and their suppliers will be prosecuted for breaching federal drug laws even if they lived in a state where its medical use was legal.

When Ms Raich was told of the decision, she decided she would still use the drug and would not let the Government kill her.

The court said the US had not reached the point where "the right to use medical marijuana is fundamental and implicit in the concept of ordered liberty". The decision highlights the conflict between the federal government, which declares marijuana an illegal controlled substance with no medical value, and the 11 states that allow its use for patients with a doctor's recommendation.

California was the first country that allowed patients to use marijuana with a doctor's recommendation back in 1996.
